Bottom Line
Rear drum brakes are still found on certain models because they are cheap, reliable enough for everyday driving, and last a long time in low‑stress situations.

Design & Looks
Drum brakes sit inside a sealed cylinder behind the wheel. This compact package frees up space for styling cues like larger rear‑wheel arches or a cleaner brake‑dust look. Many budget‑friendly sedans and compact SUVs keep the rear drum to keep the rear axle simple and lightweight, which helps designers meet tight packaging targets.
Performance & Mileage
In daily commuting, a drum brake can provide plenty of stopping power. They excel at low‑speed braking, where most city traffic stops occur. However, they are prone to fade under repeated heavy use, such as mountain driving or track days. Because they are less aggressive than disc brakes, they cause less wear on tires and can slightly improve fuel economy – every pound saved from a lighter brake assembly helps mileage.
Price & Rivals
Cost is the biggest reason manufacturers keep drums at the rear. A drum‑brake set can be 30‑40% cheaper than a comparable disc‑brake kit. For entry‑level cars that compete on price, that saving is passed to the buyer. Competing models that opt for rear discs usually charge more but market the benefit as superior stopping performance and easier service.

FAQ
- Do rear drum brakes affect fuel efficiency? They are a bit lighter than discs, so the small weight saving can translate to a fraction of a MPG improvement.
- Can I replace rear drums with discs myself? It’s possible, but it requires new calipers, mounting brackets, and sometimes wheel‑hub changes. Most owners let a shop handle the swap.
- Are drum brakes safe for highway driving? Yes, for normal traffic they provide adequate stopping power. Heavy‑load or high‑speed braking benefits more from discs.
